One hypothesis that has been proposed regarding the origin of life suggests that life evolved from an "RNA world" to today's "DNA world." Considering the properties of RNA and DNA molecules, which questions would direct an investigation of the most insightful test(s) of this hypothesis?

Could RNA have provided a template for DNA assembly, thereby enabling a more stable molecule that is replicated more accurately?

Explanation:

Based on the information provided within the question it can be said that the question that would best bring about investigation onto this hypothesis would be "Could RNA have provided a template for DNA assembly, thereby enabling a more stable molecule that is replicated more accurately?" as it brings up the most important topic, of how could RNA have developed into DNA?

the reason the two sea urchins don't compete with each other for food, resources, etc. is because the urchins have adapted to the environment but they have also adapted to each other. this is most likely because the genes of the sea urchins.
